Smiths mantle clock project

Sorry I could not get back yesterday. My other love is genealogy my family tree.   If you are sure, you now have it sorted. I was going to suggest taking the chime leavers off and starting from the beginning and describing what each part will do when the chiming starts and how to set it.

I wouldn’t mind doing that anyway OH if you could help. Now I have a clue as to what’s supposed to be happening it would be good way to help it make complete sense.

If you want to start at the beginning, I suggest you remove all parts from the front. When you have done that, put this piece in, move the wheels around, and tell me, in what position is the wheel at next to the fly? Also on the strike, side after the hammer has lifted where that wheel that has a pin next to the fly is. They both need to be around the 10 number on a clock face as that will be the warning for both chime and strike.

Ok, I have taken everything off. I have put that lever back in, haven’t tightened the screw yet. When the hook has stopped the wheel, the other wheel with the pin is at about 2.00 position. On the strike side, when you say after the hammers have lifted, do you mean at the top of the strike or just as they begin to lift?  Just as they lift, the pin is at 10 position,  just before they drop the pin is at about 12 position.

Chime side. The wheel with pin next to the fly needs to around the 10. This gives it the warning, anything over that and the warning is too short.

The strike side. After the hammer has lifted and just dropped, the wheel with the pin needs to be at about the 10. Just put on the green arrow part and the blue arrow gathering pallet, part with the black arrow. When green arrow part drops into the pallet (blue arrow), the two parts should be in the slot brown lines. Make sure when it is trapped the hammer is not on the rise.

I’m not clear about the pins lying at the 10 position OH

Strike side.  After the hammers have dropped the wheels still spin slightly and stop randomly, the pin doesn’t always stop at 10 position. If I hold the wheels, at the moment the hammers fall the pin does seem to be around the 10 position. Is this how you mean to check it?

Chime side.  The pin is at 2 position when the hooked levers are engaged with the other wheel. How do you get it to be in the 10 position?

I put those parts back on. After the hammers have dropped and the lever comes down and is trapped, the pin on the wheel is stopped at 12 position by the green lever part. No hammers are moving.

OH,  I think this may be easier hope you don't mind.

The chime side, you have the pin on the 2nd wheel in the hook, therefore the lifting pallet must have the pin on the lever in one of the recess, if not loosen the screw behind the lifting pallet turn the pallet till the pin is housed.

Next put the minute hand on and take it round till the lever it is lifting drops , now the chime is set up.

Next, the strike,

Take the pallet lifter off.

Lift the rack (the one that counts the strike) past the lever (the one with the green arrow) and let the lever fall and rest the rack on it.

Next, turn the wheel with the pin on it till it hits the lever stop (if the hammer is half way through a strike just turn it till it has dropped) , now put the lifting pallet on with the lever pin housed in the recess.  

All done,

Some  adjustment may be needed on the chime hook so it is free when at the apex of the lever rise, to do this just loosen the screw on the hook lever and adjust it till it is just clear of the pin.  

Also the chime sequence will need to be set, however that is simple and will help when you get this done.

I think it’s correct. With a bit of luck I’ll find out when I put the movement back in the case. If it runs,  all well and good. If not, well I have learned a bit regardless. That’s worth something. Thanks for your help. I’ll let you all know the outcome.

It’s been running and chiming since Friday. I set the time properly on Saturday and it is still correct. I know it has issues and needs some repairs carried out but, all things considered, it wasn’t even working when I got it. 

Thanks everyone for the help and advice.

It all looks good, however no sound? Just check that when it chimes the 1/4 past the hour the four beats (the hammers fall in this order) are 1,2,3,4,  if they do not, most likely the westminster chime will sound odd. Well done though :woohoo-jumping-smiley-emoticon: this is a hard movement to start on, get yourself a time only and take it apart and bush it even if it does not need it as this will be the most common issue you will find on any type of movement.

I don’t think it was chiming in the order you mentioned JD. I Think it’s ok now, although the half hour does not sound as I had expected it. I have some short clips of the quarter, half, quarter to and hour.

    • Something else to remember here, here in America we have a culture of anti-monopoly. Much of the rest of the world has not established any infrastructure to combat the power they create for themselves. What Switzerland and ETA did was essentially block all competition. If you want something fixed you can only ever go to authorized service centers which ETA/ swatch and the Swiss government will have full control over. One of the largest monopolies in the world is a company we should all be somewhat familiar with, Debeers. Yes, The Diamond People, Debeers! They own every aspect of the diamond industry except one. One that never sold out to them and one that Debeers is force to bend to, to get what they need from them. This one hold out is where you get your "Hand Cut" diamonds from. These are the Jewish diamond cutters located in several ares including New York City, USA, Antwerp, Belgium and a couple other locations. To the best of my knowledge Debeers is not allowed to conduct any business here in america because of our strict anti-trust (anti-monopoly) laws. However, they are forced to use representatives to deal with the diamond cutters in New York. Just over the boarder in Canada these laws do not exist and Debeers has massive operations in full swing up in the arctic circle. Has anyone watched the show on the Discovery channel, "Ice Road Truckers"? They were basically the delivery service for the Debeers mines. Sadly there is not a thing Cousins or anyone can do about this. Because the Swiss government is in bed with the Swatch group, they can make any law they like and exclude everyone as they have here. This is a shame for small business watch repairmen, hobbyists and large distributors like cousins. I hope that The Swatch Group notices a decline in their sales because of this decision, but I seriously doubt it. One final thought, Debeers has had some pretty serious competition recently in the area of Synthetic diamonds. The Russians have developed and refined the process of manufacturing synthetic to the point where they are almost completely indistinguishable from the natural diamonds Debeers peddles. Debeers has taken to using lasers to micro-etch serial numbers and company logos on every diamond over a certain carat weight. And, as I read it, Debeers recently began manufacturing and selling synthetic diamonds because it couldn't shut them down. A new version of "If you can't beat them, join them", lol.
    • Thanks man! Haven't had a chance to work on it yet but soon. I appreciate your help. 
    • Nothing too special. I use a drafting table at the far end of my studio over the garage.  
    • But does this mean that a clock like this will not function correctly, or for long? The sub-min I have has kept perfect time for the six months I've owned it. It has a weighty, solid feel, and doesn't (at least outwardly) look cheap or inferior.
